LIQUID-FUEL BURNER.

To all whom it may concern B it known that I, GEORGE VAN BALLE- oooiJnNa citizen of the United States, residing at Zion. in the county of Lakeand State of Illinois, have invented certain new and useful Improvementsin Liquid-Fuel Burners, of which the following is a specification.

The invention relates to liquid fuel burners and has as an object theprovision of a burner adapted to be used for heating furnaces. A furtherobject of the inven tion is the provision of a burner which shall beeasy to start ,into operation, safe in use, and which will burn liquidfuel efficiently and without danger of becoming readily stopped up.

An illustrative embodiment of the invention is shown in theaccompanyingdrawing in which Figure 1 is a plan view.

Figure 2 is a central vertical section of a base casting.

Figure 3 is a central vertical section on line 3-3 of Figure 1 partly inelevation.

Figure 4 is a bottom plan view partly broken away of the air supplycasting.

Figure 5 is a detail vertical section on an enlarged scale on line 55 ofFigure 1.

Figure 6 is a plan View of one of the elements of Figure 5.

Figures 7 and 8 are horizontal. sections on lines 77 and 88 respectivelyof Figure 5, Figure 7 being shown on an enlarged scale.

As shown the device comprises a base casting 10 having a depressedcentral portion 11 adapted to receive fuel to be used in the initiationof the use of the burner to generate gas from fuel present in thegenerating portionv To provide an overflow in case excess of fuel isintroduced into depression 11, when starting, there is shown a drainpipe 12 passing through a boss 13 in the casting 10 and which is open atits upper portion. To receive a flame spreader 14 shown in Figure 3 andtoy admit a supply of air underneath the same there is shown a centralupstanding collar 15 having a sleeve 16 supported interiorly andconcentric therewith as by means of ribs 17. The spreader 14 is shown asprovided with a threaded hollow stem 18 and is formed so that itsskirting will overhang the collar 15. The spreader 14 is preferably madeof brass for readiness in casting and to avoid rust. A central flamereceiving but- Application filed November 13, 1923.

by means of a screw threaded opening.

ton 19 is shown supported upon a ribbed stem 20 extending into thehollow in the stem 18 and having lugs 21 to provide a space betweenitself and the spreader 14. By connection of a pipe 22 to the lowerportion of the sleeve 16, liquid fuel may be allowed to flow through.the stem 18 and to overflow upon the upper portion of the spreader 14.when it will fall into the de pression 11 and may be there ignited toinitially heat the gas generator 23 to start the burner.

The generator 23 is shown as comprising a main casting 24 seating uponand extending through an annular boss 25 at the central portion of theair supply casting 26. The projecting portion 27 of the gas generator isshown as interiorly threaded to receive a plug28 having a jet opening 29at its central portion.

@Within the portion 27 there is shown a cage or shell 30 havingoutwardly flared projections 31 and 32 carried by its outer wall anddesigned to keep the shell centered in the interior of the portion 27and spaced above the plug 28 therein. the shell 30 there are shown aplurality of carbon sticks 33 which by becoming heated are adapted tohave a catalytic action upon the liquid fuel and to assist in producinggas therefrom. The upper portion'of the body 24 is shown as threadedboth interiorly and eXteriorly. A shell 34 is shown as en gaged upon theexterior threads and a shell 35 upon the interior threads pro iding anWithin annular chamber between the two shells in i which there are showna plurality of carbon sticks 36 to further assist in the gasifying ofthe fuel.

As ameans for circulation of the liquid fuel below and above the sticks36 there is shown a channel 37 in the top edge of the body 24. Avertical passage 33 is shown communicating wit-h the channel 37 and.with a passage to the exterior closed by plug 39 which may be removed toallow sec i ment to drain out or into which a cleaning wire may beintroduced.

The shell 34 is shown as closed at its top by means of an interiorlythreaded cap 40 to which a fuel supply pipe 41 is connected las T e pipe41 is shown as interiorly threaded adjacent its end and a small pipe 42having its outer end 43 closed is screwed into the pipe 41. The pipe 42is shown as provided with a series of openings 14 for delivery of fuelto the generat'on Preferably the generator is attached to the air supplycasting 26 as by means of screws 45. To supply air for combustion thereis shown a plurality of collars 46 formed integral with the base castingl0 and an air casting 26 having downwardly turned collars 4:? adapted toseat over the collars 4-6 and to rest upon the edges of casting 10.

'At the central portion of the casting 26 there is shown a collar 4-8throughwhich air entering through the collars. .46 may be drawndownwardly and mixing with the gas from jet 29 may burn, the resultingjet of flame. impinging upon the cast iron button .19 and beingdeflected by the same and by the spreader 14. The device is preferably Isupported by a plurality of leveling screws 49 engaging lugs 5.0, threesupports being shown for a stable support.

Fuel may be supplied to the device by means of a main supply pipe 51connected by means of a tee 52 to the pipes 22 and all,

valves 53 and 54': being provided for control of the course of the fuel;It will be understood that the main fuel pipe 51 and the pipes 22 and d1may bear any desired relation to the burner with the tee and the valvespreferably arranged exteriorly of the furnace in which the burneris'installed. Then it is desired to start the burner the valve 54 willbe closed, generator 23, however havring its annular chamber betweenshells 34 and 35 and the interior of the shell 30 filled vwith fuel. Thevalve 53 will then be open to tion.

' adapted for burning kerosene.

allow fuel to enter the depression 11 after which it will be closed andthe fuel in the depression ignited. 'When the generator 23 has beenheated sufficiently to produce gas from the liquid therein, the valve 53may be opened when the flame rising about the branches of the aircasting 26 will keep the air passages and the generator 23heated to ahigh temperature effectually producing a gas from the liquid fuelsupplied; through a pipe 41v and preheating the air for combus- Thecontinuous skirt'55 of thebase casting 10 is preferential only.- v VMinor changes may be made in the physical embodiment of the inventionwithout departing from its spirit.
